[2023] Unique buffs/nerfs are the way to balance aram

Looking at the 13.7 patch notes I saw 3 interresting nerfs to champions:

Karthus: Passive Duration: 7 seconds ⇒ 5 seconds

Sion: Passive Form Lifesteal: 100% ⇒ 50%

Veigar: E Cooldown: 20/18.5/17/15.5/14 seconds ⇒ 23/21.5/20/18.5/17 seconds

And I think targeting the pain points of champions in ARAM directly with small adjustments in numbers (not more than 5% IMO) is the best way to balance ARAM going forward.

My suggestiong of a change is giving bard more chimes/less chimes needed per lv and remove healing reduction to allies for him. Currently he has a large dmg buff and dmg taken buff and it makes him very feast and famine and unfun.

Any other unique buffs/nerfs for champions?
